Definitions
- the invention relates to a mobile crane and its use for stacking of containers.
- the container a bridge in a cable-operated load suspension device (spreader).
- the Containers can be stacked within the bridge width of the gantry crane can be discontinued.
- Devices of this type can be used in a roadworthy design Independent wheel drive and all-wheel steering with steering locks of up to 45 or have 90 degrees.
- the drive energy is generated by diesel gensets and converted to diesel-hydraulic or diesel-electric for speeds of 90 m / min in horizontal travel and 40 m / min for trolley travel.
- this stacker either has one Rope hoist or a special, designed for container transport, Lifting and lifting equipment.
- This vehicle which is below or the side of the boom of a driver's cab, can in front of the Front axle of the undercarriage picked up, stacked and also for Be kept horizontal. In very long vehicles, it can during horizontal travel in the steepest boom position of the container also in Area above the front axle, however 20'containers or longer considerably laterally across the vehicle width stand out.
- the vehicles have a rear steerable axle, so that it is possible to swivel in stacking aisles on a container space.
- the tramline is also to dimension it so broadly because these stacker only in front of the Can stack the front axle and therefore always across the container stacking area must be positioned.
- Mobile cranes are also known from DE-C2 2450003 or Mobile cranes on road-running undercarriages in the longitudinal central axis of the Vehicle a turntable above the rear axle or between the axles (DE-C3 2544525, EP-A-0 543 276 EP-A-0611725), which also with counterweights for a telescopic boom with luffing mechanism, as well as an operator cabin is provided.
- a - swiveling - operator's cabin Use both for horizontal travel and for crane operation Find.
- Such mobile cranes can operate at speeds of 60 km / h or can be driven more, but can only be stacked on stationary ones Use locations.
- Container transport can only be done in front of the vehicle respectively;
- the route width is relatively large, which makes the ratio between stacking area and driveway area becomes very unfavorable.
- the vehicle has a low one Stability, especially when loaded containers with weights up to 45 t to be transported and / or stacked.
- the transport trip there is a very high tire load on the front axle of the Vehicle, which limits the transport load and / or tire damage or damage to the roadway due to excessive specific wheel loads cannot be avoided.
- the driver of the Stackers a poor view.
- the invention is based on the problem of a mobile crane for the Stacking and horizontal transport of containers and similar loads to propose even on unpaved terrain, where the disadvantages of Prior art devices avoided the benefits of each
- vehicle types are used and those with the lowest possible Device dimensions a maximum possible load dimension can be mastered can, with the smallest possible maneuvering effort and high stability.
- the ratio of stacking space to the necessary stacking aisle is for reasons the economy of space should be as large as possible.
- the solution is characterized in that starting from a normal Mobile crane with telescopic boom this is modified so that the Wheel axles are provided with steerable wheels, so that a very low one Turning circle is created and a turntable is provided, including the superstructure has the maximum width of the vehicle, but at most the width of the Vehicle including the wheels when the steering is turned and the Turntable in the middle between the wheel axles, i.e. also in the center of the Under car is arranged.
- This solution enables the vehicle to be maneuverable in all directions around the longitudinal and transverse axes of the crane, which are considerably higher than previously known stacking cranes lies and is only comparable with the maneuverability of the Gantry cranes for container handling.
- An essential purpose of the central The arrangement of the turntable lies in the central introduction of all static Forces and thus an even load distribution on all wheel axles of the Vehicle, be it two, four or six axles.
- This Load increase for the crane relieves or reduces the load on the individual axes the tire load at maximum load.
- This is supplemented by a Transport storage for the containers to be transported, always as possible lies above the projection surface of the undercarriage.
- the focus of the Containers are located between the side wheels approximately in the middle of the Vehicle transverse axis held so that from the sum of the Counterweights and the recorded load weights as possible uniform distribution on the individual wheels. At the same time, through this measure in turn is the effective max. Tropic and the necessary Stacking aisle width considerably reduced.
- each wheel axle or for increased demands on the Maneuverability or off-road capability also individually driven and each wheel can be adjusted individually in its swivel direction, preferably with a steering angle of up to 45 degrees or even 90 degrees.
- the mobile crane like this also be moved in the "crab walk” when a uniform impact of all Wheels of the mobile crane is set. This makes maneuvering very tight Spaces possible.
- the vehicle is preferably provided with an autonomous travel drive for horizontal travel, for example a diesel unit, the axle drives and / or the individual wheel drives being implemented as sensitive hydraulic drives via corresponding converters and hydraulic pumps.
- the drive energy can be used for the lifting functions of the device, for example the hydraulic cylinder of the telescopic boom and the support cylinder, which is preferably designed as a hydraulic cylinder.
- these sub-functions also include the option of rotating the operator's cab on the rotary table, which can also be swiveled hydraulically, in order to be able to swivel it from a lateral loading position to a forward-facing horizontal travel position and to provide the driver with a corresponding view .
- provision can also be made to move the cabin on the turntable vertically into a position which enables the driver to optimally handle the device. If there is little available space, the driver's seat can, as is known per se, only be pivoted in the cabin.
- the truck has a length / width ratio of four axes about two. The width results from the width of the goods to be transported Containers whose long center of gravity with a small safety distance of 10-30%, preferably at least 70% of its width, above that Undercarriage lies, and the width of the holding members of the boom and Support cylinder or luffing gear.
- Additive can be provided to cross the undercarriage and Longitudinal stabilizers improve their stability and also a To protect the tires in that no inclination of the Undercarriage is due to the tire deflection. Can also during of container transport, the support on the undercarriage - if the Container is set down at all - be attached so that here too the load is evenly applied to the undercarriage.
- the rotary table is, as is known from other similar systems, by means of Slewing ring or friction gear in the undercarriage can be swiveled through 360 ° arranged.
- the driver's cabin is preferably on the turntable itself - in the direction of travel seen - arranged on the right next to the luffing area of the boom at the front edge of the turntable, while the rear edge - from the driver seen - the placement of the counterweights and the rocking axis of the
- the boom and the support cylinder are reserved.
- the counterweights are optimally used.
- the counterweights can also serve as side supports for one about the level of the roof of the driver's cab arranged rocker for the Cantilevers are provided. This high position of the rocker joint enables with a horizontal boom, a commercially available container with the help to capture the spreader that is right on the floor next to the mobile crane has its stacking place.
- the position of the driver's cab on the "Front" edge of the turntable limited by that for holding one Containers required clearance from the ground, which by the Bottom edge of the container during its pick-up and Inward pivoting movement in the direction of the vehicle axis is limited.
- the vehicle can also be equipped with safety technology, preferably with electronic sensors that both limit the Tire load as well as stability depending on the Cantilever position, both its luffing position and its extension length considered.
- Other critical stability parameters such as inclination of the Undercarriage in the longitudinal and transverse directions and position of the driver's cabin, can be included in the monitoring.
- the telescopic boom is designed in its retracted position so that a container can be picked up directly to the side of the mobile crane, while its maximum extended position must be adapted to the maximum stack height.
- the support cylinder can be arranged so that it is arranged almost parallel to the boom in the steepest boom position, so that there is a maximum free space in the longitudinal direction above the undercarriage for Cont a inertransport.
- Fig. 1 shows the mobile crane with four axes F 1 to F 4, the undercarriage U wear.
- a turntable D is arranged centrally on the undercarriage U has a 360 ° swivel range.
- the driver's cabin K is on the turntable with rotary degree of freedom KR and vertical degree of freedom KV, as well as that Counterweight G arranged.
- This view is between the two elements the telescopic boom in the transverse axis QA, the support cylinder Z, the Load suspension device L and the spreader S can be seen.
- the spreader S holds you 40 'container 1 or alternatively - dashed - a smaller 20' container 6 in Transport position in the longitudinal direction to the undercarriage U.
- FIG. 2 shows the mobile crane according to FIG. 1 in a front view in its entire width b, which corresponds to approximately half the length 1 of the vehicle.
- the undercarriage is connected via the turntable D to the superstructures, which are all arranged on the turntable or turntable D.
- the driver's cabin K can be seen here in the loading position, as in Fig. 1.
- an axis W is arranged as a luffing axis for the boom A, which - here consisting of the telescopic parts A 1 and A 3 - is drawn with the associated extension positions S 1 and S 3 for the swivel joint of the spreader S.
- Am The head of the boom is the load-carrying means L rotatably as a connection to the load attachment means, the spreader S, both of which are connected by the swivel joint or swivel joint S 3 or S 1.
- the support cylinder Z is on the turntable at a point on a projection line stored between the center of the turntable, represented by the Longitudinal axis LA and the rocking axis arranged radially on the outside of the turntable W.
- the cylinder CLOSED bearing can be swiveled with the turntable coupled.
- the other end of the support cylinder is in the swivel joint ZO with the lower section A1 of the telescopic boom A connected.
- the support cylinder Z can extend the axis point ZO by the rocking angle WW, represented as a line of motion of the pivot point ZO, until the boom A is in the horizontal position, represented by the position of the Swivel bearing S 4 of the spreader S for receiving the container 4 from Floor next to the mobile crane.
- the other dash-dotted lines SW 1, SW 3 and SW 5 indicate the different swivel angles of the associated Spreader - swivel axes S 1, S 3, S 5.
- the position of the container 1 is Transport position for this container, as is also shown in Fig. 1.
- Fig. 3 shows of the mobile crane only the undercarriage U with the different chassis axles F1 to F4 (Fig. 2), to the individually steerable Wheels FR are coupled.
- the Load introduction takes place via the theoretical load introduction point as Intersection between the transverse axis QA and the longitudinal axis LA over the in Fig. 1 and Fig. 2 shown rotary table D in the undercarriage U.
- Der The undercarriage distributes the load evenly over the axles F that contribute to this if necessary with suitable and known differential gears, Handlebars and / or converters FA are provided so that the axle loads can be transferred evenly.
- the Axes F1 and F2 are assigned to a common turntable UD; in the same way, the axles F3 and F4 can also be coupled via a common turntable.
- the wheel position of each axle should be controllable separately, preferably each Wheel, as shown on axes F1 and F4 in Fig. 3, individually be adjustable.
- This very agile vehicle has a width of the Undercarriage b during the entire width of the space with the steering turned takes a measure b2.
- This dimension b2 is slightly smaller than the width b4 a route in the curve, where b4 is the narrowest route width for the Undercarriage U represents, while b6 is the wheel position for the narrowest Includes route width.
- FIG. 4 an alley PG of a stacking area P is shown in the event that a mobile crane is to travel diagonally through this alley.
- the turning of the wheels FR to the axis of the vehicle F is shown here at 45 °.
- the vehicle needs a route width b5 that is approximately twice the width b; with the inclusion of a 40 'container, this results in a necessary width of the stacking alley b3 which is only slightly larger than the width which the vehicle itself occupies. From Fig. 3 it can be seen that the turning radius of the vehicle corresponds only to approximately twice its width b.

Description
Wegen der seitlichen Lasteinleitung und fehlender Kompensation des Lastgewichtes können diese Stapler am Ladeort nur mit ausgefahrenen Stützfüßen betrieben werden, was den Umschlag entsprechend zeitaufwendig gestaltet. Der Wendekreis ist bauartbedingt relativ groß.
Ergänzend ist es natürlich möglich, die Antriebsenergie des autarken Fahrantriebes auch über einen Generator in Elektroenergie umzusetzen, um so die nötige Energie für die Antriebe und die Beleuchtung oder sonstige Subfunktionen bereit zu stellen, soweit dies nicht über Batterien möglich ist. Zu diesen Unterfunktionen gehört neben der Beleuchtung und Signalanlage auch die Möglichkeit, die Bedienerkabine auf dem Drehtisch, der ebenfalls hydraulisch schwenkbar ist, rotatorisch anzutreiben, um diese von einer seitlichen Verladeposition in eine vorwärts gerichtete Horizontalfahrtposition schwenken zu können und dem Fahrer eine entsprechende Sicht zu ermöglichen.
Für die Stapelfunktion und zur besseren Übersicht für den Fahrer kann außerdem vorgesehen werden, die Kabine auf dem Drehtisch vertikal zu verfahren in eine Position, die dem Fahrer ein optimales Hantieren des Gerätes ermöglicht. Bei geringem verfügbarem Platzangebot kann erforderlichenfalls der Fahrersitz, wie für sich bekannt, auch lediglich in der Kabine geschwenkt werden.
